================================================================
If your kernel has CONFIG_VSERVER_AUTO_LBACK=y then loopback addresses and
things will be assigned and made visible in your guests automaticly. You can
disable that on by guest basis by doing:
{{{
- echo "~lback_remap" > /etc/vservers/xyz/nflags
+ echo "~lback_remap" >> /etc/vservers/xyz/nflags
echo "~hide_lback" >> /etc/vservers/xyz/nflags
}}}
If your kernel has CONFIG_VSERVER_AUTO_LBACK option disabled you can still
get automatic loopback addresses on by guest basis by doing:
{{{
- echo "lback_remap" > /etc/vservers/xyz/nflags
+ echo "lback_remap" >> /etc/vservers/xyz/nflags
echo "hide_lback" >> /etc/vservers/xyz/nflags
}}}
(util-vserver 0.30.214 or newer needed)

+ === binding to address 0.0.0.0 binds only to single IP ===
+
+ Newer Vserver from 2.3 series allows administrator to enable special handling
of network contexts for guests with single IP only. Default value for this
option is compiled into kernel as CONFIG_VSERVER_AUTO_SINGLE. When it is
enabled any service configured to bind to all available IP addresses will bind
only to single IP configured in {{{/etc/vservers/guest/interfaces}}}. It will
not even bind to loopback interface.
+
+ To enable special handling of network contexts in guests with a single IP do:
+ {{{
+ echo "signle_ip" >> /etc/vservers/xyz/nflags
+ }}}
+
+ Similarly to disable this option if its enabled in kernel do:
+
+ {{{
+ echo "~signle_ip" >> /etc/vservers/xyz/nflags
+ }}}
